摘　　要：在北京市门头沟碧琨种植中心的温室大棚茄子上释放巴氏钝绥螨后,调查统计对茄子上西花蓟马及东亚小花蝽数量的影响。结果表明:释放巴氏钝绥螨对温室大棚茄子上的西花蓟马的种群数量在其高峰期具有一定的压低作用,尤其是释放200头/m2巴氏钝绥螨效果更好。温室大棚茄子上自然发生的本地天敌东亚小花蝽的种群数量,在各处理间的总体趋势相同,随着西花蓟马的数量变化而变化。The control effects of Amblyseius barkeri on Frankliniella occidentalis on the eggplants and their natu- ral enemy Orius sauteri in the greenhouse in Bi-Kun Plant Center of Mentougou district, Beijing were investiga- ted. The results showed that a certain role of A. barkeri in suppressing the population of F. occidentalis was observed by releasing A. barkeri 200 individual/m2. The population of their local enemy O. sauteri occurring naturally in the greenhouse had the same trends among all the treatments and varied with the F. occidentalis quantitatively.
